Your cousin is preparing a classic volcano for her school's science project using baking soda and vinegar, but she is disappointed that her volcano is not as exciting as the one she saw online. Knowing that you're taking chemistry, she asks for your help. Based on what you learned in experiment 2, which of the following changes is likely to result in the most exciting volcano?A. Combining the reactants in their stoichiometric ratio to ensure maximum production of product.
B. Adding excess vinegar to drive the reaction equilibrium toward products.
C. Using more baking soda, because it is responsible for producing the CO2 gas that erupts from the volcano.
D. Forming the baking soda into a cube so it will react all at once.

Explanation:

Carbonic acid (H2CO3) is formed when vinegar (CH3COOH) and baking soda (NAHCO3) are mixed which is unstable and decomposes to produce CO2. This is what will make the bubble rise and fizz steadily to the top of the volcano.

CH3COOH + NAHCO3 ⇄  CH3COONa + H2CO3

H2CO3 ⇒  H2O + CO2

Vinegar is dilute Acetic acid, the reaction equilibrium will be shifted to the product side upon the addition of more vinegar. Hence, more H2CO3 will form, that is more CO2 will form. This would lead to more bubbles arising.

Therefore,  the answer is option B - adding excess vinegar to drive the reaction equilibrium to the product side.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

answer: they produce more slow than unicellular organisms.
